In Wayland, Solaar cannot find active process name causing Solaar to print a traceback and Rules do not work

Created by: lieryan

Running Solaar in Wayland causes a lot of crashes that looks like so:

ERROR:logitech_receiver.listener:processing Notification(10,255,00,00,000000)
Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'startswith'

Digging into diversion.py, it looks like Wayland never send NET_ACTIVE_WINDOW, so the global variables active_process_name and active_wm_class_name are never set.

Possibly because of the traceback, it looks like that the Rules system doesn't work at all.
